Ionization in circuit breaker is facilitated by___________?
Correct answer: D. all of the above
- A. high temperature
- B. increase of mean free path
- C. increasing field strength
- D. all of the above
Explanation
Ionization is promoted by high temperature, which increases particle energy, a longer mean free path, which allows more ionizing collisions, and stronger electric fields, which accelerate charged particles. Therefore, all three effects facilitate ionization.
